A magnetic tape cartridge includes a magnetic tape, and a storage medium in which information on the magnetic tape is stored. The magnetic tape has a recording surface. Data is recorded in the recording surface by a magnetic head in a state in which the magnetic tape is made to travel. The magnetic head is disposed at an inclined posture with respect to a width direction of the magnetic tape along the recording surface. Angle adjustment information obtained at a data recording timing which is a timing at which the data is recorded in the recording surface is stored in the storage medium. The angle adjustment information is information for adjusting an angle at which the magnetic head is inclined with respect to the width direction along the recording surface.

Data is recorded in the recording surface by a magnetic head in a state in which the magnetic tape is made to travel. The magnetic head is disposed at an inclined posture with respect to a width direction of the magnetic tape along the recording surface. Angle adjustment information obtained before the data is recorded in the recording surface is stored in the storage medium. The angle adjustment information is information for adjusting an angle at which the magnetic head is inclined with respect to the width direction along the recording surface.

At least a portion of a first servo mark is read using a first read head during a rotation of a disk, the rotation comprising no more than 360 degrees. At least a portion of a second servo mark is read using a second read head during the rotation of the disk. Tracking positions of the first read head and the second read head are determined during the rotation based on reading the first servo mark and the second servo mark.

A data storage device may be destroyed by suspending a transducing head above a data storage medium prior to inducing contact of the transducing head with a first layer of the data storage medium in response to a signal from a controller. Deflection of the transducing head can then be increased to penetrate to a destroy depth in a second layer of the data storage medium that is maintained while the data storage medium spins. The controller may then issue at least one data read command to access data from the data storage medium and when a data read error is received, the data storage medium and transducing head can be verified as destroyed and incapable of accessing data previously written to the data storage medium.

A multi-layer piezoelectric microactuator assembly has at least one poled and active piezoelectric layer and one poled but inactive piezoelectric layer. The poled but inactive layer acts as a constraining layer in resisting expansion or contract of the first piezoelectric layer thereby reducing or eliminating bending of the assembly as installed in an environment, thereby increasing the effective stroke length of the assembly. Poling only a single layer would induce stresses into the device; hence, polling both piezoelectric layers even though only one layer will be active in use reduces stresses in the device and therefore increases reliability.

A computer program product for orienting a head, according to one embodiment, includes a computer readable storage medium having program instructions embodied therewith that are readable/executable by a controller to cause the controller to determine a desired pitch for transducers of a magnetic head for reading and/or writing to a magnetic tape, and are readable/executable by the controller to cause the controller to cause a mechanism to orient the magnetic head towards first and second positions to achieve the desired pitch when the tape travels in first and second directions, respectively. Outer data transducers of the third array are about aligned with outer data transducers of the second array when the magnetic head is positioned towards the first position, and the outer data transducers of the third array are about aligned with outer data transducers of the first array when the magnetic head is positioned towards the second position.

A system may compensate for skew in a patterned medium, such as but not limited to a self-assembling bit patterned medium, with a write pole separated from a data storage medium by an air bearing. The write pole being connected to a controller. The data storage medium can have a plurality of magnetic islands arranged in data tracks with each data track having a track center. The write pole may be selectively shifted from the track center by the controller to compensate for a skewed write pole configuration.

The present disclosure generally relates to a voice coil motor (VCM) yoke assembly mounted to an actuator block for a data storage device. One or more fastening mechanisms couple the VCM assembly to the actuator block. The fastening mechanisms are coupled to the VCM assembly by one or more soft mounts. The one or more soft mounts reduce undesirable movement of the magnetic recording head by spacing the VCM assembly from the actuator block, yet still ensuring the VCM assembly is properly coupled to the actuator block.
